I was contacted for a phone interview availability. After first phone interview, there was another phone screen. Next round was on-site interview for 4 hours where I was interviewed by 5 people one on one. The on-site interview also involved a case study presentation that I had to work on prior to the interview. Most of the phone interview questions were repeated so I would have preferred to speak with both the interviewers together or just have one phone screen. The entire interview process was very long. ~ 3 months. Although, the feedback immediately after the interview was VERY positive, I received just an auto generated email stating the position was filled 3 weeks after my on-site interview. I reached out to the recruiter asking for feedback and I was told that some hard to please people on the panel were not satisfied by my spot on case study and answers. Thanks and good luck!
